Duplex receptacles for general use shall be installed approximately fifty feet (50') apart in all corridors and within twenty-five feet (25') of ends of corridors.
8. A nurses' calling station shall be installed at each patient bed and in each patient toilet, bath and shower room. The nurses' call-in toilet, bath or shower rooms shall be an emergency call. All calls shall register at the nurses' station and shall actuate a visible signal in the corridor at the patient's door, in the clean workroom, soiled workroom and nourishment station of the nursing unit. In multi-corridor nursing units, additional visible signals shall be installed at corridor intersections. In rooms containing two (2) or more calling stations, indicating lights shall be provided at each calling station. Nurses' call systems which provide two (2)-way voice communication shall be equipped with an indicating light at each calling station which lights and remains lighted as long as the voice circuit is operative.
9. A manually-operated, electrically-powered fire alarm system which will serve to alert all areas of the hospital when activated shall be installed in each facility. In multistory buildings or in multi-building facilities, the signal shall be coded or otherwise arranged to indicate the location of the station operated. Pre-signal systems will not be permitted, except when telephone switchboard is attended at all times.
10. To provide electricity during an interruption of the normal electric supply that could affect the nursing care, treatment or safety of the occupants, an emergency source of electricity shall be provided and connected to certain circuits for lighting and power.
11. The source of this emergency electric service shall be an emergency generating set when the normal service is supplied by one (1) or more central station transmission line(s) or an emergency generating set or a central station transmission line, when the normal electric supply is generated on the premises.
12. The required emergency generating set shall be located on the premises and shall be reserved exclusively for supplying the emergency electrical system. The emergency generator set shall be of sufficient kilowatt capacity to supply all lighting and power load demands of the emergency system. The power factor rating of the generator shall be not less than eighty percent (80%).
13. Emergency electric service shall be provided to at least the following circuits:
